From: Tiezhu Yang Date: Wed, 31 Dec 2025 07:19:10 +0000 (+0800) Subject: LoongArch: Remove is_entry_func() and kernel_entry_end X-Git-Tag: v6.19-rc4~11^2~10 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e5416d63bcba2bcc280d170eaf66775771892be;p=thirdparty%2Fkernel%2Fstable.git LoongArch: Remove is_entry_func() and kernel_entry_end For now, the related code of is_entry_func() is useless, so they can be removed. Then the symbol kernel_entry_end is not used any more, so it can be removed too.
